Barbara - I'm worried he will hurt himself.
Maggie - I agree with the philosophy, but I don't think he really has liability. He keeps brushing over that and wants to come down with the contracts. He made the comment to me he wants to do the job "under the table" which is why he can charge so little. He is trying to get by as work is slow.
Amma - I know, another thing to factor in. And, what if I'm not happy with it at all?
Moonpi - that is true. My house was built in 1898 and I am 52. Shingles are good for about 25 years but metal roof will outlast me and probably my house as well. :) It is a New Englander and I think the metal roof will also take away from its character. And actually, I'm not sure I even like the looks of them.
